All Time Low’s Alex Gaskarth Has Shared A Voice Memo Of The Riff That Became ‘Birthday’

All Time Low's 'Birthday' is already a certified banger, and we've pretty much had it on repeat for the past two weeks since it was released.

Now All Time Low frontman Alex Gaskarth has let us all in on a part of the writing process, sharing a voice memo of the riff that became 'Birthday'.

Posting a screen-captured video of his phone, Alex has shared the recognisable riff from the song, saying "Voice note of the main riff in 'Birthday'. Love going back and finding these little starts that grew up to be real songs."
